What a great idea to use Dr Bronner's soap! I think I'll have to try that. Do you put the solution on your wipes and then store it in the warmer or do you get them wet as you use them?

I put the solution on the wipes and store in the warmer; we go through them all in a day and have never had them get dingy/smelly. Dr. Bronner's is awesome, a container of it has lasted us months and months. MUCH cheaper than any other wipe specific solution I have seen.
